Hi Angela,
I agree that your species belongs to subgenus Acmira, but I'm not sure that
it is A. catherinae, I can not see in your image the cover on distal end of
the hook, as well as, the basal swelling of the antenna is not very
pronounced. I think you should try again with other photographs, make
clearer the image of hook shape, prostomium and antenna (its shape and
extension).
According to my notes, in the case where the hook is covered, then your
species would be closer to A. (Acmira) sp C Gaston 1984, but this
undescribed species was cited from northern Gulf of Mexico. But, if the
hood is absent, then the most closer species is A. (Acmira) strelsovi
Hartmann-Schröder & Rosenfeldt 1990, the shape of the hooks, prostomium,
antennae and branchiae distribution are similar, the problem is that this
species is from the Antartic.
Good luck.
Angel de León
